Expansion of High-Speed Railway Sub-grade CMA Modifier Applied Research

摘要：

Shiwu railway passenger dedicated railway network planning 揺ight vertical and eight horizontal?railway trunk line, speed, quality standards high, especially after the settlement of roadbed construction request for the amount of not more than 15mm, this expansive soil sub-grade construction has set higher requirements. Articles for SHIWU Railway Passenger Line of expansive soil sub-grade construction of high standards and strict requirements of the features discussed in detail the ecological CMA.. (changing the montmoriuonite抯 absorbent) modifier modification principles, construction methods, quality control points, through the CMA modifier improved the amount of spraying times and sprayed expansive soil test analysis to determine the applicable passenger dedicated railway expansive soil subgrade construction process, quality control methods to guide construction of similar projects will have a positive learn.

关键词： expansive soil sub-grade CMA principles of ecological construction technology modifier modification.
